AUTOMOBILE-RADIATOR.

" iecflcaton of Letters Patent.

Patented Nov. 8, 1910.

Application tiled May 26, 1909. Serial No. 498,540.

T o all whom it may concern:

Be it known that l, llaman Din'rz, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Autonmhile-Radiators; and I do hereby declare the following to be a full, cle: and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

My invention relates to radiators such as used in connection with automobiles, and is particularly directed to the improvement of the construction -of the hood ledgiug; and to the above ends, the invention consist'sof the 'novel devices and combinations of devices'hereiafter described and defined in the claim.

Hitherto, it has heen customary to forni the hood lodgingI iu several pieces, and to solder the same to the sheet metal outer frame of thc radiator` and it. has also heed customary to solder the upper edge of the back plate of the upper tank of the radiator tfothe hack upper corner of the radiator frnlne In. practice, the Se a-rately formed hood lodging` was irst sol ered to the outer frame of the radiator', and thereafter t-he back of the upper tank, was sol dered to the said outer frame, at 1radically the Same place, so that very great caw had to be taken to prevent the second soldering from loosening the soldered joint of the hood ledgin ,'and thereby causing leaks Ain the top o the tank, where they are very difficult to repair. Furthermore, the solder vicintly ofthe hood lodging to theouter frame, in itself, is un expensive process.

In accordance with my invention, I forin the hood lodging `integral with the sheet metal outer frame of the radiator, by rollin r or ressilig the ed' e of said frame, and Holt erthe upper e rc of the back late of the upper tan rot t ic radiator to tie ledg- 'mg or rear portion of the said frame, so

thutthere is only one soldered joint in the of the'ledgi i. This accomplishes severa important resuts. In the first place, it veryi greatly reduces the cost of applying tlie ledgmg in the second-place, it makes they lodging and the rear edge of the radiator frame very much stiffer than the old ',construo'tion; and in thethird place, by

eli'oiinatiuoone of thc solder joints, it removes tho danger of: opening of soldered joints hy second soldering at approximately the same place. i

lu the accompanying drawings which illustrate the invention, like characters indi rate like parts tlirouo'liout the several views.

`lieterriiu; to the rawings: Figure. 1 is a view in front cleval ion with some arts broken aivay. and some parts removed, illus- (rath-ng` my invention as applied to a radiator of the type linoivn as the McCord automobile radiator: Fig. 2 a side elevation of the part' own in Fig. 1, some parts beimgr hrolreii ay; and Fig. 3 is an enlarged fragmentary viewin side elevation, some parts beingl'l'rokcn away and some parts beupper tanligot the said radiator into ,whichv the hotvvater from the envinc is delivered through a pipe 4 indicated:` by dotted lines only in Fig. l. .The numeral 5 indicates the engine hood which' isshown only in Fig. 3. The vertical tubes and tins of the radiator are-not. shown in the drawings, and may be of any suitable construction.

The hood lodging 6 is formed integral with the outer fraaie 1 and is joined to the rear edgeof the latter by a pressed or rolled bead or rib 7, which very greatly stitfens the rea-r edge portion of the said framofl.A The hood ledgin'g 6 is odset pr pressed 8,0 that. .it stands inward ofthe'body portion of the traine '1,2 and the front end of the engine P is adalpted to reatthereon as shown hood o in Fig. 3. T ie back plate 3 of the upper tank 3, at its upper er ge, is soldered to the ledging, and furthermore, it has beeny found i that the radiator m be constructed therewith at a very consi erablyreduced oost.V

What claim is? In an automobile radaoi, the'coinbina 'pion with un 4inner radiator frame, o'f an y out'r frame'inclosing the said inner frame,

I6' und the said outer frame being formed from sheet metfnl and having its rear edge rolled bxpres'sed to ferm a hood ledgin and sti ching Bead, which latter integral y connects lsad ldgng to the 'said outer frame, Substa-ntmll'yf ns described. -110 1n testn'llony 'whereof l n'lx my signa-ture 1n presence 0ftvfri witnesses.
